A 100-year-old woman says she enjoys a beer and some potato chips every night.

When a 100-year-old person gives diet advice, the whole world listens. And when San Francisco resident Matilda Curcia celebrated her 100th birthday this week, she gave the rest of the world a gift and said the secret to long life is beer and potato chips.

"I have no pain and do my exercises every day. And have my beer. Eat my potato chips. That's about all,” she told NBC San Diego when asked what she thought was the secret to her long life.

Curcia says she stays in shape by walking regularly with her friend and neighbor Mickey, who was born just four days after Curcia. The two celebrated their 100th birthday with a joint party. Sometimes they ride bikes together, too. The only other thing Curcia could think of was that she drinks one beer and eats three potato chips every night.
